Answer? Appreciate the help

Answer y = -2

Step 1.

In order to make an equation with 1 variable, substitute the right side of the first equation for x in the second equation for 3x + 5y = 20. In the example all instances of x in the second equation will be replaced by 10.

Rewrite the x so it will be 3 · 10.

3 · 10 + 5y = 20

Step 2.

Multiply 3 by 10.

3 × 10 = 30

Step 3.

Subtract 30 from both sides.

30 + 5y - 30 = 20 - 30

Step 4.

Simplify.

5y = -10

Step 5.

Divide both sides by 5.

1. Divide the numbers.

5 ÷ 5 = 1

= y

2. Simplify.

Apply the fraction rule.

3. Divide.

10 ÷ 5 = 2

Y = -2
